Tailboards

Available in 3” – 24” sheave diameters for wire rope ranging from 5/16” – 1-1/4” with capacities up to 60 tons. Please specify bronze bushings or roller bearing options. With the convenient side open feature our tailboards are easy to reeve the block without removing any fitting from the end of the wire rope. Proof testing and recertification available. Custom tailboards available upon customer requests.

NOTE: When ordering,please specify:size,block number,bronze bushed or roller bearing,and wire rope size.NOTE: Tailboard does not contain the spool that is required with the hook (L-5-H) and shackle (L-5-S) snatch blocks.

402 TAILBOARD (All Alloy)

Entire block made from heat treated alloy steel. Use of heat treated alloy gives block only 60% of the weight of blocks of comparable capacities.

NOTE: When ordering,please specify:size,block number,bronze bushed or roller bearing,and wire rope size.NOTE: Tail board does not contain the spool that is required with the hook (416) and shackle (417) snatch blocks.

401 TAILBOARD ( All Alloy )

Entire block made from heat treated alloy steel. Use of heat treated alloy gives block only 60% of the weight of blocks of comparable capacities.

* Ultimate Load is 4 times the Working Load Limit.†May be furnished in other wire rope sizes.

NOTE: When ordering,please specify:size,block number,bronze bushed or roller bearing,and wire rope size.NOTE: Tail board does not contain the spool that is required with the hook (434) and shackle (435) snatch blocks.

Mobile Load Testing Services and Inspections

We offer inspections and mobile proof test services for product verification, break testing, and load testing to ensure compliance for all tailboards and sheaves we sell and repair. Our mobile proof test services are available throughout the United States. In addition to our mobile load testing services we have stationary test beds to service Oklahoma, Texas, Kansas, Wyoming, North Dakota, New Mexico and all surrounding areas.

6 x 19 and 6 x 37 classification ropes provide an excellent balance between fatigue and wear resistance. They give excellent service with sheaves and drums of moderate size.
6 x 37 classification because of the emphasis on fatigue resistance the problem of choice is greatly reduced. Although there are exceptions, the constructions in the 6 x 37 classification are primarily designed to be the most efficient for each rope diameter. As the rope size increases, for instance, a large number of wires can be used to achieve required fatigue resistance and still those wires will be large enough to offer adequate resistance to abrasion. It should be noted that the greater the number of wires make the 6 x 37 classification more susceptible to crushing. However, this can frequently be overcome by an independent wire rope core (IWRC) and by the use of well designed sheaves and grooved drums. 6 x 19 classification has outer wires larger than 6 x 37 classification, and therefore its resistance to abrasion is increased, but its fatigue resistance is decreased. 6 x 19 classification is a good rope to withstand abrasion or crushing on the drum.

Ferrules are made of high strength alloy steel and feature a two-piece wedge that is rifled to provide more gripping surface on the wire rope strands and greater holding power. Machined wedge-type ferrules permit the make up or repair of chokers and winch lines in minutes - No molten socket metal or swaging equipment is required.

Winch Line Tail Chain is a flexible attachment for use on the end of wire rope. Primarily intended for use on truck and tractor winch lines. Length specified is exclusive of hook. Use same size chains as wire rope. The hook is dropped forged alloy steel and heat treated for extra durability. The hook is designed to prevent wear on wire rope.
